Thought I'd share a few pics of a fabrication and install project at the shop just now. We previously worked on this customer's Mercedes CL65 rear diffuser last year

He was so happy with the result, naturally he had to have one done for his Maserati Grantourismo convertible! The factory diffuser is a little lackluster (no offence Pinninfarina!

), so we planned on adding something with a bit more Italian flare...
BTW - Hearing an Italian V8 engine note in a shop full of American muscle is quite unusual!! It's like hearing an opera singer at a Metallica concert!!
